ABSTRACT:
The present invention provides methods and apparatus for installing a cylindrical body, having a plurality of external axial splines, within a stack of annular plates, said plates having radially inner teeth for meshing with said splines. The method includes the placement of a cylindrical alignment tool, having a plurality of external splines, in a position subsequently to be occupied by said cylindrical body. The annular plates are placed about said alignment tool, with the teeth of said annular plates meshing with said alignment tool. Then, an axially compressive force is applied to said stack of plates to maintain axial alignment of the teeth of adjacent plates. This axial compressive force is supplied by a high pressure fluid which is communicated to a piston engaging said stack of plates. Then, the alignment tool is removed while said axial compressive force is retained on said stack of plates. Finally, said cylindrical body is inserted into the stack of plates, while the axial compressive force is still being applied, thereby holding the radially inner teeth of the annular plate in axial alignment.
